- Specification of Letters Patent.

Application filed March 21, 1914. Serial No. 826,142.

To all whom it may concern:

Be it known that I, EDWARD BLooM, citizen of the United States, residing at Haledon, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in WVarping-Machines, of which the following is a specification.

This invention relates to warping machines, and it has for its principal object to provide a warping machine with a simple and reliable means for stopping the rotation of the reel when a predetermined length of warp has been wound on the reel and for indicating by an alarm device the stages in the operation when the lease cords should be introduced in the warps and the end of the winding of a section or other definite length of warp is approaching.

According to this invention the reel-driving mechanism includes a disconnective clutch-connection whose movable clutch member is controlled by a shiftable powertransmitting means which is moved from the reel in the direction to shift said member for breaking the clutch-connection and which is provided with a normally active detent which, on said movement of said means, locks the latter against return, leaving the power cut off until the operator reestablishes it; preferably the mechanism for actuating said means is a pattern mechanism having a disconnective connection with the reel (whereby it is driven) so that on 'disestablishing said connection the pattern mechanism may be moved to allow reestablishing the aforesaid clutch-connection on releasing the detent, and also'to reset the pattern mechanism, all without disturbing the reel. According to this invention, further, means, operated from the reel through a pattern mechanism, is employed to actuate an alarm device at certain stages, for instance, those indicated above.

In the accompanying drawing, Figure l is a side elevation of a fragment of a warping machine including my improvements; Fig. 2 is a front elevation of so much of the machine as directly includes said improvements; Fig. 3 is a view similar to Fig. 2, but on a larger scale and showing only the pattern mechanism and the alarm device; and, Fig.4 is a plan view of the improvements.

, The frame a, reel 1), having its shaft 0 journaled in the frame in the usual manner, and also having the driving band d, the rotary shaft 6 carrying a friction wheel 7 to engage the band 01 and so drive the reel, the

lever g in which said shaft is journaled and the lever it operated from suitable means, such as a treadle (not shown), so as to effect movement of lever 9 up and down to shift the friction wheel f into and out of contact with the band 03, are or may be all substantially the same as in any warping machine of the type of that herein shown, to wit, a horizontal warping machine. In the present instance, the pulley i rotated by suitable means lncluding the belt 1, is freely revoluble on the shaft e and forms one member of a clutch, of Which the other member is the part marked 70 in Fig. 2, being splined on said shaft. On shifting this member to the left in Fig. 2 the power is transmitted from i to 6; when shifted to the right, 2' rotates idly. V In a bracket Z projecting from the frame 1s fulcrumed a lever m having a fork a eugaged in the peripherally grooved collar o of the clutch member 7a and being normally influenced by a spring p to maintain clutch member is engaged with the other clutch member-pulley 2'. Pivoted to one arm of this lever, which overhangs a part of the frame a, is a pendent detent'm.

In brackets q secured to the frame above the pulley shaft 6 is arranged the shaft r afiording a fulcrum for four levers, one of which, 3, is connected with the lever m by the rod 6. In these brackets is journaled a shaft 10 having a handle '2) at one end whereby it may be manually rotated and carrying a sprocket wheel 10 over which extends an endless pattern chain at, provided with (in the present instance) four balls 3 the lever s rests on this pattern chain in vertical alinement with one of these balls, so that, as the chain is advanced once in each circuit there of the lever is elevated. lhe shaft it carries a fixed clutch member sand on it is splined a movable clutch member 2 having a wormwheel 3 meshing with the worm 4 on the shaft 0 of the reel. For moving the clutch member 2 I provide the sliding fork 5 arranged on the shaft 0 and engaged in the groove 6 of said clutch member, said fork being normally forced to the right in Fig. 1 by a spring 7 coiled between the fork and the left-hand bracket 9 and thereby maintaining the disconnective connection 2 normally established. 8 is a set screw for securing the fork in a position where said connec- Patented Mayan, 1915.

tion 2 is disestablished. The other three i levers (9) in the group including. the lever s. are vertically alined with and adapted to be actuated by the three remaining balls on the chain 00. Respectively attached to them are the branches 10 of a chain 10 which is in turn connected to the elever 11 for actuating a bell or other alarm 12 (the details of Whose mechanism it is unnecessary to v describe),

Operation: In the winding of each, sec-. tion or other length of warp on the reel the alarm deviceis actuated three times, (in the present instance), first to notify the at -p tendant when to insert the first lease cond, next to notify when to insert the second lease cord. and finally tosignal the approach, of the point in, the section where it shouldbe cut off thereupon the. reel isautomatically brought to a standstill. These opera: tions are performed by the levers 9 and 5. i he de of their arrangement, rom right to left in Fig, 1;, as: they are, succes;v sively lifted. by the balls on the pattern, chain. The reel, upon, being brought to a stop bythe elevation, of lever s, is main-v tained: at a standstill bythe detent mf which, on the movement, of lever,- m to, shift clutch member 70 out of clutching engagement with pulley 2', seats upon the frame and; thus prevents return, movement of said lever and; the clutch member. Having cut ofi and, tied. the

, section thuswound on, the reeland attached the. end of the-new section tothe reel the attendant employsfork 5todisestablish the-connection 2. whereupon handle '11. is-turned: to shift the pattern chain forwardly just enough to clear the ball; which stopped the machine from beneath the lever s, Detent m is. thenmoved out of engagement with the frame, allowing. the lever m and conse? quently the clutch-member is to return; to their normal positions, whereby the reel is again put in motion.

Having-thus fullydescribed: my invention,

what I- claim as new and desire to secure by Letters; Patent is 1- l. In a warping machine, the combination of the frame, the reel journaled therein, an alarm device having an actuating member to be actuated, a pattern mechanism opera-. tiyely connected with and driven by the reel, and means to transmit motion to said member including. patternrmechanism-actuated devices and. a. branched flexible connection attached to said member and having its branches connected with, said. devices.

2.,I-n, a warping machine, the. combination of the. frame, the reel. journaled therein, means, to notatethe reel including a discon: nective clutch connection, an alarm device haying an actuating. member to be actuated, a, pattern mechanism operatively connected t and dr v by t e l}. patte anism-actuated means, to control said. clutch connection, and. means to transmit mo i n to said member; ineluding, pattern-mechanism-. aetuated; devices and a, branched flexible connectionattached t c-said member and,hav-. ingits branches connected. with. said. devices.

3. a, warping machine, the combinationv of the frame, the reel, journaledl therein, a pattern chain having balls arranged. out of alinement with, each other in. the length. of the. chains, reeleactuated means for ad'vanc ing the chain, a plurality of levers bearing 75. against the chain. respectively in. alinement with said; balls, an alarm device having an actuating. member, and a. branched chain attached to. said member and having. its branches respectively connected with said levers.,

In, testimony whereof I afiix my signature n nresenee: o w tn see,
